ment-s in deep well pumps, and it is an obj-ect et the invention to provide a novel and im? proved structure et' this general character embodying means whereby the traveling valve may be conveniently withdrawn from its working position Without the necessity of pulling out the working barrel.

he invention consists in the details of construction and in the combination and arrangement of the several parts of my improved deep well pump whereby certain important advantages are attained and the device rendered simpler, less expensive and otlierwise more convenient and advantageous for use, as will be hereinafter more full set forth.

T e novel features of my invention will hereinafter be definitely claimed.

lin order that my invention may be the better understood, l will now proceed to describe the same with reference to the accoinpanying drawings, wherein:

Figure l is an enlarged 'fragmentary view partly in elevation and partly in longitudinal section illustrating a barrel structure constructed vin accordance with an embodiment ci: .my invention;

Fig. if?, is a sectional view taken substantially on the line 5km-2 of Fig. fl; and

,Fig 3 is a'sectioual view taken substantifally on the line ilu-3 ont Fig. l.

As disclosed in 'the accompanying drawings, denotes a working barrel preferably of the type disclosed in my prior applicau tion, Serial No. 399,488, tiled July 28, 1920, and oit which the present application is a division., said barrel embodying the standing valve 42. Working within the barrel B is 'the travelin valve V. f The trave ing valve V is ot a conventional type andincludes the leather` cups or gaskets {4*5. .ln 'threaded engagement with the upper end vportion of the traveling valve V in a well lrnown manner Vis the lower end portion Specification c1 Letters Eaten't.

This invention relates to certain improve- Y ct the valve stem 46. The lower portion 46a of the stem 46 is angular in cross section while the upper portion lob is circular. rlhe stem 46 works through a lift cage t? operatively engaged with the upper end portion of the working barrel B preferably through the. instrumentality et lett hand threads.

The lower portion or' the bore Li8 of the cage 45.7 is angular in cross section to snugly receive t e angular lower portion 46% of the stem 46 while the upper portion of said bore of the cage is cylindrical and through which the cylindrical portion 46h ci the stein lo is snugly disposed.

he upper end portion of the stem 46 is adapted to be coupled as at 47a, in a conventional manner with the lower end portion of a pump pod 50.

Under normal conditions, the strokes ot the rod 50 permit the valve V to have its requisite reciprocation within 'the barrel B but when it is desired to lwithdraw the valve V to renew the leather cups or gaskets or to otherwise repair the valve V, the rod is pulled upwardly until the angular portion 46a of the stem 46 engages within the angular portion ot the bore 48 of the cage i7 and upon requisite rotation being given to the rod 50, the cage 47 will be disengaged from the barrel B, whereupon the valve V can be easily removed and without the necessity ot withdrawing the barrel B' and the remaining structural elements of the mechanism positioned within the tubing T and the parts carried thereby. With the valve "V removed, the Working barrel and the parts carried thereby can be readily removed by engaging within the upper or open end ofthe barrel B a suitable shing tool.

From the foregoing description it is thought to be obvious that a deep well pump constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled an'd'operated, and it will also be'obvious that my invention is susceptible of some change and modification without departing from the` principles and spirit thereof and for this reason l do not wish to be understood as limiting mysell" to the precise arrangement and formation of the several parts herein shown in carrying out vmy invention in practice enoeptasjhere- Mtl v, carried bythe traveling valve and disposed through the Cage, a portion of the bore of the cage being angular in cross section and the lower portion of the stem of the traveling valve being of a cross section similar to the angular cross sectional portion of the bore of the cage.

2. A deep well pump comprising, in combination, a tubing, a working barrel positioned within the tubing and provided with a@ stand valve, a traveling valve working within the barrel, a cage carried by the upper end portion of the barrel, and a stem earried by the traveling valve and disposed through the cage, a portion of the bore of the cage being angular in cross section and y the lower portion of thestem of the traveling valve being of a cross section similar to the angular cross sectional portion of the bore of the cage, saidcage being in threaded en-I gagement with the barrel.

3. In Combination with the Workingbarrelfor a deep well pump, a traveling valve working therein, the bore of the barrel at the upper part thereof being angular in cross section, and a stem carried by the traveling valve and disposed throughthe angular portion of the bore of the barrel, the lower portion ofthe stern being of across section similar to the angular cross sectional portion of the bore of the barrel. I

4. In combination with the working barrel for a deep well pump, a traveling valve working within the barrel, a cage carried by the upper portion of the barrel, and a stem carried by the traveling valve and disposed through the eage, a portion of the bore ofthe cage being angular in cross section and the lower portion of the stern of the traveling valve being of a cross section similar to the angular cross sectional portion of the bore of the cage.

In testimony whereof I hereunto affix my signature.
